Vibratory Centrifuge for Coal

2 Mass vibration system, consisting of:

  • Small Mass:
    .Screen basket, Inlet pipe, shaft and bearing housing
  • Large Mass:
    -Product housing, Cross member, Steel frame
  • In-between the 2 masses are rubber buffers
  • The vibrations are generated by 2 counter rotating unbalance weights.
  • This gives vibration in the resonance range, somewhat less then natural vibration. The amplitude of the empty machine can be set by adjusting the pre-tension on the rubber buffers.
  • When the feed is increased the load in the basket increases, increasing the small Mass, thus giving a vibration coming closer to the natural frequency. This automatically increases the amplitude.
